MKMapView 添加图片

From: http://www.cocoachina.com/newbie/basic/2012/0201/3926.html

以下为两张图片。如下：

适当的代码段添加如下annotation. MapAnnotation是实现了MKAnnotation的NSObject类:

CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(latitude, longitude);

MapAnnotation *annotation = [[MapAnnotation alloc] initWithcoordiante: coordinate];

[map_view addAnnotations: annotation];

[annotation release];
